The first officer I was flying with today asked if we wanted anything and I said, “green tea.” So he comes back with this one and I spent a good portion of the flight (while serving passengers) trying to figure out what it was. My first thought was sencha and lemon. Definitely citrus. I thought it was a bit bitter but not overly so. Could have been just because of how long it was steeped. Pretty sure it was probably in there around 5 minutes. The weird part was when I got to the bottom of the cup it was intensely bitter. Kinda weird. Overall, not bad but I probably won’t get it again.
